Risk

Risk is a solo question-card quiz. Nine face-down cards sit in three rows: the top row is hard questions worth 30 points, the middle row is moderate questions worth 20 points and the bottom row is easy questions worth 10 points. Tap a card, answer its multiple-choice question and build your score. One hidden card per game pays double points for its row. Tap, click or use number keys 1-4; no network or accounts needed.
